Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Sour Milk Ginger Bread
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 350°F (175°C).
In a bowl, mix the molasses and sour milk.
In another bowl, sift together the flour, baking soda, ginger, and salt.
Make and bake the batter
Combine the wet and dry ingredients, then add the melted butter.
Beat the mixture vigorously until well combined.
Pour the batter into a buttered shallow pan.
Bake for 25 minutes.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Molasses
- Adds dark color, sweetness and a rich, strong flavor to the bread.
- Sour milk
- Its acidity reacts with the baking soda so the bread rises and becomes tender.
- Flour
- Provides the structure that sets the batter into a crumb as it bakes.
- Baking soda
- Reacts with the acidic sour milk and molasses to produce gas that lifts the batter.
- Butter
- Adds fat for moistness and a tender texture in the finished bread.
The step that matters
Beat the mixture vigorously until well combined. Beating develops gluten in the flour, which gives structure, but overbeating can make the bread tough. The baking soda starts reacting as soon as it meets the acidic liquid, so the batter should go into the pan and oven promptly to keep the rise.
Swap the ginger
How well each one fits the dish's main ingredients (molasses, milk, flour, butter):
- Cinnamonfits better
- Nutmegfits better
- Jalapenofits about as well
- Gingerthe original
Fit is the average pairing score against molasses, milk, flour, butter. Candidates are from the same food group and used in at least 100 recipes.
